Scavenge Port Inspection onboard Ships

Scavenge inspection or scavenge port inspection refers to inspection of piston, piston rings, cylinder liner, etc. of the main propulsion engine through scavenge ports. This helps for detecting leakages from the piston and cylinder cover, if any. Jacket cooling water and lubricating oil pumps should be running during the scavenge port inspection. Scavenge inspection is carried out partly from under piston area and partly from scavenge air receiver. Inspection procedure is following.

Make sure that vessel has necessary permission from port authorities or bridge for main engine immobilization.
